Max Wipfli a819f98956 LibGUI: Fix off-by-one error in rendering of highlighted text ...

This fixes an off-by-one error in TextEditor's rendering of the syntax
highlighting as generated by Syntax::Highlighter and its subclasses.

Before, a single character span was e.g. (0-3) to (0-3), but this was
considered invalid by GUI::TextRange. Now, a single character span would
be e.g. (0-3) to (0-4).

This fix requires all Syntax::Highlighter subclasses to be adjusted, as
they all relied on the previous implementation. This will then also fix
a bug where single-character HTML tags wouldn't be highlighted.
